…Is because they don’t work! They do keep babies attached to you. That’s about it. I have harnessed the babies twice for preschool drop off instead of using the stroller. Both times it did not work well. Why? Because babies still want to go where they want to go, which is usually not where you’re going. Since the harness hooks on their back, they are in the lead instead of you. And unlike pulling a dog leash, if you pull on the baby harness, you yank the poor kid of his feet and he cries. Which gets you even worse mommy PR than you already had for leashing your baby in the first place. So the baby toddles to the end of his rope, and then you’re in a stand still because you don’t want to go his way, but you can’t guide him to go yours.
And as usual, twins add a special extra complication to the matter. Baby A toddles to the end of his rope in one direction, and inevitably Baby B toddles to the end of his rope in the opposite direction, leaving me with both arms extended stuck in the middle. If I pull on anyone, they fall over and cry. The only solution is to drop a leash handle, but then that baby takes off un-tethered and I’m back to grabbing a baby and then mad dashing to catch the other. They both end up crying anyway because they didn’t get to go where they wanted to go, and I end up wrestling 2 squirming babies under each arm.
I think I’ll stick with the stroller, which contains them better and always goes the direction I want it to go!
